need urgent help

I had a laptop 4530s, and he come with hp protected tools. One of them is drive encryption with mcaffe endpoint encryption. Now i couldn´t start my pc because i got an error EE050014 "File acess error". What could i do to solve this problem?

How could i recover my data and bring back my laptop to original factory settings?

Someone told me to use f11 key at windows startup but I have tried it many times nothings happened?
